Ok so I came across a nice little acrylic tank on the side of the road in good shape couldn't pass it up but anyway I'm going to drill it I was originally going to drill the bottom but decided that would use too much real estate it's only like a 25 gallon. So I decided I'm going to drill the side and build a overflow box for it now the problem I'm coming across is what type of piping should I use I have been scouring the Internet for days trying to find a good option. Anyway my dilemma is can you do like a herbie style coming off the side or what are the downfalls of just getting a bulkhead and just having a hole in the side that's a drain with a valve to control the flow? I plan on running a large sump and this mostly just a frag tank since I have some extra kessils just laying around and enough equipment to probably build two more tanks lol so I can use a large return like a mag5 or 7 I'm not necessarily worried about noise I already have two tanks in my room feet from my bed so I'm not concerned with that but is there a reason people don't just drill a hole and seal with bulkhead when it comes to the side of the tank. Or if it's not recommended to drill just a hole what style would be better coming from the side of the tank?
